After I've been playing by SR at live gig level's....about an hour or so into things I begin to get a uncontrolable hum. I just replaced all the tubes..TAD, and gold tipped Tung Sol 12ax7s across the board.\
Any idea's what my be doing this? My TAD power tubes glow Hot Blue when they're really running. Thats ok right?
